How to Iterate Over a Set in Ruby - Step by Step Examples

How to Iterate Over a Set in Ruby ?

To iterate over a set in Ruby, you can use the each method or a block.

In this example,

We create a set of strings named string_set containing various strings.
We use the each method or a block to iterate through each element in the string_set.
Within the loop or block, we perform a specific operation or print each string element.

require 'set'

string_set = Set.new(['Apple', 'Banana', 'Orange'])
string_set.each do |string|
  puts string
end

Apple
Banana
Orange

In this example,

We define a set of integers named int_set containing various integer values.
We use the each method or a block to iterate through each element in the int_set.
Within the loop or block, we perform a specific operation or print each integer element.

require 'set'

int_set = Set.new([1, 2, 3, 4, 5])
int_set.each do |number|
  puts number * 2
end

In this tutorial, we learned How to Iterate Over a Set in Ruby language with well detailed examples.
